It looks like the msys2/mingw tool is corrupt or was unable to download all the appropriate files.
My suggestion would be:

• to make sure full access rights are given to the userid used to access the C:\Tools\vcpkg folder/files and all sub-folders/files
• to rename the _msys2_ folder found in C:\Tools\vcpkg\downloads\tools\msys2 to _msys2.old_ and try again
• hopefully vcpkg will download/recreate the msys2/mingw tools
• when all works then delete/remove C:\Tools\vcpkg\downloads\tools\msys2.old folder.
